Redefining the grid-tie inverter is a tall order, but that’s exactly what Xantrex has done with the Xantrex GT 3.0 Grid Tie Solar Inverter.
The three-kilowatt high performance PV string inverter offers superior PV energy harvest, easy installation, state-of-the-art design and high reliability.
It’s also setting a new standard for inverter cost by offering the best price/performance ratio in the industry!

Easy Installation |
The Xantrex GT 3.0 Inverter makes life easier for installers of solar power systems. Its modular design and integrated, lockable 600 volt PV/Utility disconnect switch eliminates the need for costly external disconnects and results in simpler, cleaner installations.
Its attached wiring box provides protection for all AC and DC connections, eliminating exposed wiring during inverter installation and removal. The wiring box includes eight 3⁄4 inch knockouts and easy access DC and AC terminal blocks that accept wire sizes from #14 to #6 AWG.
The GT 3.0 is packaged in a rugged NEMA 3R rated enclosure for reliable outdoor installation. To make mounting single and multiple inverters simple, the GT 3.0 incorporates a slotted, hook-style back plate. For large systems, multiple inverters can be mounted side by side centered on standard 16” stud spacing to reduce visible conduit and make installations look more attractive.

Improved Local Display |
GT inverters come standard with a backlit 16-character two line Liquid Crystal Display. Useful for troubleshooting and system feedback, the LCD provides a variety of information including up to the minute inverter power, daily and lifetime energy production, PV array voltage and current, utility voltage and frequency, time online “selling” today, fault messages, and two installer customizable screens. Tapping a finger close to the LCD activates the backlight display. With each tap, the display cycles through all the communication screens. The LCD is always on standby, ready to provide information even at night. When inverters are daisy chained using standard CAT5 Ethernet cable, each inverter display will report the output of the entire system in addition to individual inverter output.
|
Standard Communications |
Our GT 3.0 offers an isolated RS232 port and two Xanbus RJ45 communication ports. Unlike competitive inverters, no additional communication ports or cards are needed to connect a PC. The LCD can be used simultaneously, even when a PC is connected to the RS232 port. Download the GT Solar Inverter Viewer software.

Superior PV Energy Harvest |
Engineered to make the most of a PV grid tie system investment, our GT 3.0 provides high power conversion efficiency, excellent thermal performance, and rapid Maximum Power Point Tracking.
Rapid Maximum Power Point Tracking
The Xantrex GT 3.0 Maximum Power Point Tracking algorithm’s rapid response to insolation events, like moving cloud coverage, maximizes the output energy of connected PV strings. It has a wide input range from 195 to 550 volts DC ensuring the inverter begins to operate earlier in the day, and is more resistant to array shading. It also allows more flexible array sizing.
|
High Efficiency |
For small and large systems, our GT 3.0 offers high peak and average efficiency to convert all the valuable energy produced by solar panels into useable electricity.
|
Excellent Thermal Performance |
As temperatures climb, solar panels and inverters heat up and produce slightly less energy. To minimize energy loss due to heat, our GT 3.0 has a large aluminum heat sink to keep its electronics cool even in the hottest climates. Unlike competitive inverters that start to derate as early as 25°C (77°F), the GT 3.0 provides 3000 watts of power up to 30°C (86°F) and 2,500 watts of power up to 45°C (113°F). So all the energy produced by the solar panels is efficiently converted to AC power and sent to the utility grid. For added protection from heat in desert extremes or south facing inverter installations, an optional fan kit can be ordered.
|
High Reliability |
To ensure the GT 3.0 is a dependable, high-quality product, Xantrex engineers have tested it extensively during the design process using an evaluation method called Highly Accelerated Life Testing. HALT combines powerful thermal and vibration technologies to stress a product beyond its specifications. This enables our engineers to find and fix product defects that may not be discovered by testing methods typically used by other inverter manufacturers. Our sophisticated HALT techniques go beyond conventional testing, which results in improved product reliability and quality.
The GT 3.0 was also thoroughly field-tested. Prior to market introduction, the GT 3.0 logged more than 15,000 test hours in home installations.
To ensure reliability, the HALT chamber combines powerful thermal and vibration technologies to test a product and its components beyond product specifications.
